[libvirt] [PATCH] Fix compile warnings in virsh vcpupin

[Daniel P. Berrange]

The 'char *cur' variable was being assigned from a
'const char *' string, thus discarding constness.
As well as causing a compile warning, it masked a
piece of code which attempts to assign to the
previously const string.

* tools/virsh.c: Fix const-ness of 'cur' variable in vcpupin
